CATransaction allows you to make batch updates to the Core Animation render tree, and it also allows to trigger implicit animations just by setting layer properties inside of a CATransaction.
CATransaction allows you to make batch updates to the Core Animation render tree. It is most used to override default animation timing functions, durations, etc. or to add a completion block to an animation that doesn't expose one explicitly.
CATransaction allows to trigger implicit animations just by setting layer properties inside of a transaction block. Animating the position of a layer in Objective C:
[CATransaction begin];
[CATransaction setAnimationDuration:0.5];
layer.position = newPosition;
[CATransaction commit];
or the same in Swift:
CATransaction.begin()
CATransaction.setAnimationDuration(0.5)
layer.position = newPosition
CATransaction.commit()
For more information, see the Apple Documentation for CATransaction.
